Pipe centrifugal pump
ISG type vertical pipe centrifugal pump is also called pipeline pump, centrifugal pump and pipeline centrifugal pump, single stage centrifugal pump, vertical pumps, mudline booster pump, heat pump, circulating pump etc, are our technical institute and domestic pump expert jointly choose excellent domestic hydraulic model, adopt IS type centrifugal pump and SG type pipeline pump performance parameters, on the basis of general vertical pipeline pump to clever combination design and manufacture, simultaneously according to use temperature, medium and other differences, based on ISG type series pipeline pump to derive applicable hot water piping pump, high temperature corrosion-resistent chemical pipeline pump and pipeline oil pump. This series of products have high efficiency and energy saving, low noise, reliable performance, etc. Comply with the latest national machinery department JB/T53058-93 standard request, design and manufactured according to the international standard ISO2858.
features
1 pipeline centrifugal pump is vertical structure, inlet and outlet dimension is the same, and is located in the same central line, can like valve to be installed in pipeline, compact and beautiful appearance, cover an small area, building investment is low, if plus shields can be placed for outdoor usage.
2 pipeline centrifugal pump impeller is direct installed on the long shaft of motor, the axial dimension is short, compact structure, pump and motor bearing allocation is reasonable, which can effectively balance pump operation generated radial and axial load, so as to ensure the smooth operation of the pump, little vibration, low noise.
3 pipeline centrifugal pump shaft seals use mechanical seal or mechanical sealing combination, using imported titanium alloy sealing rings, medium-sized high-temperature mechanical seal and using cemented carbide materials, wear-resisting seal, which can effectively prolong the mechanical seal service life.
4 pipeline centrifugal pump installation and maintenance is convenient, without dismantling pipeline system, just discharge pump couplet seat nut, then can pull out all rotor parts.
5 pipeline centrifugal pump can according to use requirements,ie flow and head request, to adopt pump series and parallel operational mode.
6 pipeline centrifugal pump can according to pipeline layout requirement to adopt pump vertical and horizontal type installation.
main usages
1 ISG type vertical pipeline pump, for conveying water and chemical and physical properties similar to water other liquids, suitable for industrial and urban water supply and drainage, pressurized water supply in high-rise constructions, garden irrigation, fire pressurization, distant distance transportation, hvac refrigeration circulation, the bathroom, etc cold and hot water circulation pressurization and matching equipment, using temperature T < 80 ℃.
2 (IRG GRG) type vertical hot water (high temperature) circular pipeline pumps are widely applied in: energy, metallurgy, chemical industry, textile, paper making, and high temperature hot water boiler hotel etc circulation pressurization system of heating of circulation and urban transportation pump, IRG type using temperature T < 120℃ GRG type using temperature T < 240 ℃.
3 IHG type vertical chemical centrifugal pump, for conveying liquids without solid particles, with corrosive, viscosity similar to water, suitable for petroleum, chemical, metallurgy, electric power, papermaking, food, pharmacy and synthetic fibre, and other departments, using temperature is - 20 ℃ ~ 120 ℃.
4 YG type vertical centrifugal oil pump for conveying pipeline, gasoline, kerosene, diesel oil and other petroleum products, conveyed medium temperature is - 20 ℃ ~ + 120 ℃.
Note: pipeline pump suction pressure ≤1.0MPa, or pump system highest working pressure ≤1.6MPa, namely the suction pressure add pump head ≤1.6Mpa, pump static test pressure is ≤2.5Mpa, when ordering, please indicating the system working pressure. When pump system working pressure is more than 1.6 Mpa, should be filed when ordering, so that pump flow parts and connecting parts adopt cast steel material when manufaturing. Environmental temperature＜40℃, relative humidity < 95℃.
